Question

what type of sampling is used when it is not possible to select individuals directly from the target population?

Answer 1

Non-probability sampling

Explanation:

Non-probability sampling is a method of selecting units from a population using a subjective method.

Answer 2

If a researcher cannot gain access to a target population, snowball sampling procedures can assist in locating subjects. In regard to sampling procedures, if a researcher wants to be able to generalize results to the total population of interest, then a purposeful sampling technique is the best approach.
